In this way, the main circuit device that controls the main functions of the exchange is housed in the basic casing to form a basic unit, and the expansion circuit device that has extended functions is housed in the expansion casing to form an expansion unit. By stacking expansion units on a basic unit to configure a switch, for example, when expanding functions such as increasing the number of lines, it is easy to stack any number of expansion units with arbitrary functions on the basic unit. I can deal with it.

(Problem to be Solved by the Invention) By the way, in the switch having the above configuration, when expanding the functions, first stack an arbitrary number of expansion units on top of the basic unit, and then stack them. The housings of each unit must be connected to each other with bolts, etc., and then the end connector of the flat cable must be attached to the connector provided on each unit to electrically connect each circuit. The procedure was complicated.

SUMMARY OF THE INVENTION In view of the above-mentioned circumstances, it is an object of the present invention to provide an electronic device whose functions can be expanded without being forced to perform complicated operations.

[Structure of the invention]

(Means for Solving the Problems) Therefore, in the present invention, one connector element is provided on the upper part of the basic unit and the upper part of the expansion unit, respectively, with the joint portion facing upward, and the expansion The above object was achieved by providing the other connector element at a position corresponding to the one connector element of the other unit located below the unit, with the joint portion facing downward.

(Function) According to the above configuration, when stacking each unit, one connector element of the unit located below and the other connector element of the unit located above are connected to each other, whereby the circuit device in each unit is connected to each other. electrically connected.

〔Example〕

EMBODIMENT OF THE INVENTION Hereinafter, this invention will be described in detail based on the drawing which shows one Example.

FIG. 1 shows an example in which an electronic device according to the present invention is configured as a telephone line exchange.

This exchange 1 includes a basic unit 10 and an expansion unit 20 installed on the basic unit 10.

The basic unit 10 has a basic housing 11,
This basic housing 11 accommodates a plurality of daughter boards (plug-in unit wiring boards), not shown. These daughter boards are attached to a motherboard 12 provided on the back of the basic housing 11, and a male connector (one connector element) electrically connected to the daughter board is provided on the upper back of the motherboard 12. 13 is fixedly installed with its joint portion facing upward.

The above-described daughter board, motherboard 12, and male connector 13 constitute a main circuit device 14.

On the other hand, the expansion unit 20 has an expansion housing 21 similar to the basic housing 11. A plurality of daughter boards (plug-in unit wiring boards) (not shown) are housed inside the expansion case 21, and these daughter boards are attached to a motherboard 22 provided at the back of the expansion case 21. ing.

At the upper back and lower back of the motherboard 22,
A male connector (one connector element) 23 and a female connector (the other connector element) 24 are fixedly provided, respectively.

The male connector 23 is installed with its joint portion facing upward, while the female connector 24 is installed with its joint portion facing downward and at a position corresponding to the male connector 13 provided on the basic unit described above. is attached to. An expansion circuit device 25 is formed by the above-described daughter board, motherboard 22, male connector 23, and female connector 24.
is configured.

The basic housing 11 of the basic unit 10 and the expansion housing 21 of the expansion unit 20 placed in the housing 11 are connected to each other by bolts (not shown), and the main circuit device 14 and the expansion housing 21 are connected to each other by bolts (not shown). The expansion circuit devices 25 are electrically connected to each other by attaching the female connector 24 of the expansion unit 20 to the male connector 13 of the basic unit 10 .

When assembling the expansion unit 20 to the basic unit 10 to configure the exchange 1, the expansion unit 20 is first placed at a predetermined position on the basic unit 10. At this time, the male connector 13 of the basic unit 10 and the female connector 24 of the expansion unit 20 are connected to each other.

That is, when the expansion unit 20 is installed on the basic unit 10, the male connector 13 and the female connector 24 are connected at the same time, and the main circuit device 14
and the expansion circuit device 24 are electrically connected to each other.

After installing the expansion unit 20 on the basic unit 10, the basic housing 11 and the expansion housing 21 are connected to each other with bolts (not shown), thereby completing the assembly work of the exchanger.

In addition, although the example shows an example in which one expansion unit is stacked on the basic unit, it is of course possible to install another expansion unit on top of the expansion unit depending on the content of the function expansion. In this case, it goes without saying that the expansion circuit devices are electrically connected to each other by connecting the male connector of the expansion unit located below and the female connector of the expansion unit located above.

Furthermore, it goes without saying that the female connector may be provided at the top of the basic unit and the expansion unit, while the male connector may be provided at the bottom of the expansion unit.

Furthermore, the present invention can be effectively applied to various electronic devices other than exchanges.

〔Effect of the invention〕

As described above in detail, according to the electronic device according to the present invention, one connector element is provided on the upper part of the basic unit and the upper part of the expansion unit, respectively, with the joint portion facing upward, and the lower part of the expansion unit is provided with one connector element. Since the other connector element was provided at a position corresponding to the one connector element of the other unit located below the expansion unit with the joint portion facing downward, when stacking each unit, the unit located below and the other connector element of the unit located above are connected to each other. As a result, functions can be easily expanded without being forced to perform complicated tasks.
